C++ and Beyond 2011 is a tremendous experience. The technical depth and C++ goodness was profound and lasted for 3 whole days (and two evenings). Thanks Andrei Alexandrescu, Scott Meyers and Herb Sutter for allowing me to crash your affair with my camera – which was perhaps too big and too advanced for the likes of me – still, I was able to capture some great content like this interactive panel on Concurrency and Parallelism with Scott, Andrei and Herb. Great questions from attendees.

[01:56] Does C++AMP build on PPL?
[02:48] What about operating system scheduling for GPU operations?
[03:49] Transition from platform-specific memory models to a standard(ized) C++ memory model (C++11′s MM, to be specific…).
[06:41] Is there a performance penalty associated with a standard C++ memory model?
[09:18] What about functional languages/techniques (with respect to parallel and concurrent programming)?
[15:44] Which performance pitfalls we may pitfall into?
[16:13] What about the work on ranges and wouldn’t they help parallelism?
[20:34] Fortran arrays have things like slices and strides. What about C++AMP?
[22:42] Parallel debugging…
